Ferrea Chevrolet BB 1.88in 11/32in 5.45in 22 Deg S-Flo LW Super Alloy Exhaust Valve - Set of 8

This set includes eight Ferrea S-Flo exhaust valves, designed for Chevrolet Big Block engines. Each valve measures 1.88 inches in diameter with a 11/32 inch stem and a length of 5.45 inches, featuring a 22-degree seat angle. These valves are crafted from a lightweight super alloy, chosen for its strength and resistance to high temperatures found in performance exhaust applications.

The S-Flo design is Ferrea's approach to improved airflow, helping to get exhaust gases out of the cylinder more efficiently. This can contribute to better engine performance, especially in modified or high-output Big Block Chevy builds. The super alloy material is well-built to handle the stresses of combustion and heat, making these a solid option for rebuilding or upgrading your engine's top end.
